摘要
厨余垃圾在生活垃圾中占比巨大,已对食品安全、自然资源可持续利用和环境造成了不利影响,故亟须实现厨余垃圾的有效处理及利用。目前处理厨余垃圾最常用的方式主要包括填埋与焚烧,但存在易产生二次污染、耗能大等问题,阻碍了其大规模应用。厨余垃圾具有有机质含量高的特性,通过生物炼制合成高附加值化学品(如有机酸等),不仅可实现产品的清洁生产,也可提高厨余垃圾的经济价值。本文首先概括了国内外厨余垃圾的处理现状及处理方法,其中厌氧消化法可清洁生产高附加值产品,展示出巨大的研究潜力。因此,对厌氧消化厨余垃圾合成化学品进展进行详细综述,最后对构建人工混菌培养体系和生物膜调控在厨余垃圾生物制造领域的应用提出了展望。
Kitchen waste,representing a large proportion of domestic waste,has caused issues in multiple areas including food security,sustainable utilization of natural resources and environment.As a result,great attention was attracted for the efficient treatment of kitchen waste.At present,the general treatment by either landfill or incineration usually results in secondary pollution or high energy consumption,hindering further application at large scale.Alternatively,the biological approach through bacterial fermentation of kitchen waste not only provides a clean and economical method,but also produces high value-added chemicals.In this review we summarized the current situation and treatment methods of kitchen waste at home and abroad.In particular,anaerobic digestion demonstrated great potential as a clean strategy to treat kitchen waste and offer high value-added products.Finally,both synthetic microbial co-culturing system,and biofilm regulation were prospected for their applications in the field of biological manufacture using kitchen waste.
